How do I allow User A to send emails as if they came from User B? She needs to be able to send most of her emails as herself, but once in a while she needs to be able to switch the "From" field to User B, so that replies are sent to him. In the old POP/SMTP setup it required created an email account for User B and removing it from the Receive schedule... Anything needs to be done in AD? Thanks for your help!
